In F# how do you pass a collection to xUnit's InlineData attribute

Question

I would like to be about to use a list, array, and/or seq as a parameter to xUnit\'s InlineData.

In C# I can do this:

using Xunit; //2.1.0

namespace C

Building further on @Assassin's brilliant answer -- now we have implicit yields you can put the test cases in an array and dispense with the yields. I would also be tempted to add a cheeky little private operator to handle the object conversions. Thus:

open System
open Xunit

let inline private (~~) x = x :> Object

let degreesToRadiansCases =
    [|
        // Degrees; Radians
        [|   ~~0.0;            ~~0.0  |]
        [| ~~360.0; ~~(Math.PI * 2.0) |]
    |]

[]
[]
let ``Convert from degrees to radians`` (degrees, radians) =
    let expected = radians
    let actual = Geodesy.Angle.toRadians degrees
    Assert.Equal(expected, actual)

let stringCases =
    [|
        [| ~~99; ~~"hello1" |] 
        [| ~~99; ~~"hello2" |] 
    |]

[]
[]
let ``tests`` (i, s) =
    printfn "%i %s" i s
    Assert.Equal(s, "hello1")
